감 품종별(도근조생, 고종시, 갑주백목, 차랑, 월하시, 상주둥시)로 감꽃을 개화기에 채취하여 동결건조 분말화한 감꽃분말에 함유된 유효성분을 분석, 비교하였다. 조지방 함량은 도근조생이 57.26%로 가장 높은 값을 보였으며, 유리당 조성은 fructose가 95~310 mg%, glucose는 75~281 mg%, sucrose가 7~28 mg%의 함유량을 나타내었고, 유기산 중 malic acid가 갑주백목(6월4일)에 225 mg%로 가장 많았고, tartaric acid도 189 mg%로 가장 많았다. 유리아미노산 중 hydroxy-L-proline은 월하시에 25.33 mg%, L-citrulline은 상주둥시(5월28일)가 58.83 mg%, L-threonine은 상주둥시(5월28일)가 11.88 mg%로 가장 많았다. 페놀산으로 caffeic acid는 갑주백목(6윌4일)이 1946 μg/100 g, phydroxybenzoic acid는 상주둥시(5월29일)가 417.8 μg/100 g, protocatechuic acid는 갑주백목(6월1일)이 181.1 μg/l00 g으로 가장 많았다. 따라서 감꽃에도 감이나 감잎에 못지않게 유용한 식품성분들과 기능성 성분들이 다량 함유되어 있어 새로운 식품 및 기능성 신소재로서의 가치가 매우 높다고 할 수 있다. This study was carried out to analyze useful components in freeze-dried persimmon flower powder made from six cultivars. The cultivars were Dogunjosang, Kojongsi, Kabjubaekmok, Chalang, Weolhasi and SangjuDungsi. Powder of persimmon flower was prepared by milling after freeze drying at -70℃. Crude lipid was the highest in Dogunjosang (57.26%). Major free sugars of the persimmon flowers were fructose (95~310 mg%), glucose (75~281 mg%)and sucrose (7~28 mg%). Major organic acids were malic acid (225 mg% in Kabjubaekmok (Jun. 4th)) and tartaric acid (189 mg% in Kabjubaekmok (Jun. 4th)). Predominant free amino acids were hydroxy-L-proline(25.33 mg% in Weolhasi), L-citrulline (58.83 mg% in SangjuDungsi (May 28th)) and L-threonine (11.88 mg% in SangjuDungsi (May 28th)). Major phenolic compounds in the persimmon flowers were caffeic acid (1,946 μg/100g in Kabjubaekmok (Jun. 4th)), p-hydroxybenzoic acid(418 μg/100g in SangjuDungsi (May 29th)) and protocatechuic acid(181 μg/100g in Kabjubaekmok(Jun. 1st)). The results suggest that persimmon flowers be potential materials as useful food ingredients.

Background: We studied the incidence of trauma caused by alcohol related accidents, and the effects that alcohol has on the occurrence, the extent, and the outcome to the patient. Methods: In our study we studied trauma patients excluding pediatric patients(15 years old and under) who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of January 1996 to 30th of June 1996, looked into their medical records, and studied the records in a retrospective manner. The trauma patients were devided into two groups, a) alcohol-related and b) alcohol-non-related. The two groups were then subdivided according to their sex, age, the time they came in, the anatomical part of the trauma, the mechanism of their injury, the extent of the injury, the length of their hospital stay, the length of their ED stay and were seperately compared and analyzed. Statistically, ANOVA and logistic regression analysis using SAS were used in the study and then was assessed in Chi-square analysis methods. Results: The total of the trauma patients, added up to 832 people, 577:male and 255:female. Among this sum, 163 trauma patients were alcohol related(male:127 & female:36). 115 people were in the age group of 21-40. Compared to the non-alcohol related trauma group, the alcohol-related group had more facial & scalp injuries and tended to come in the hours between 0-6 AM. The cause of the injuries were mostly by fist-fighting and suicide, compared to mostly accidental-slipping injuries in the non alcohol-related group. There were no difference in the degree of the injury(ISS) and the length of hospital stay between the two groups, whereas the length of the stay at the ED was longer to the alcohol-related trauma patients. Conclusion: Alcohol related trauma patients were mostly in their 20s and 30s, came to the hospital at a late time and the reason for their visit were mostly because of fist fighting. In the Emergency department, because prompt and correct diagnosis is quite difficult to make in this group, their ED stay tended to be longer. We can conclude that measuring the blood alcohol level of these patients, continuing the psychological therapy and educating people is needed.

During anesthesia, unexpectedly endotracheal tube obstruction cause seriouscomplications which require early diagnosis and immediate management. Endotracheal tube obstruction with foreign body is rare. 74 year old man was scheduled for open lung biopsy. The patient was intubated with a 7.5 mm reinforced endotracheal tube and turned to the right lateral position. After 30 minute, signs of partial endotracheal obstruction was observed including high airway pressure and decreased end-tidal CO2. A suction catheter was not deeply advanced. A wheezing - like sound was heard. We temporarily stopped the operation and turned the patient to supine. We exchanged the tube with another one and found impacted mucous secretions at the distal tip of the tube.

Acute unilateral airway obstruction may be developed immediately after general anesthetic induction. Tracheal intubation is essential procedure to support lives for who is coma or undergo general anesthesia, but several complications could occur. One of these is airway obstruction immediately after endotracheal tube insertion because of bronchial mucous plug, previous aspirated foreign body, hemoptysis ect. This acute bronchial obstruction may be manifested clinically by hypoxemia, cardiovascular instability, brain damage, if more aggravated to death due to partial or complete interruption of ventilation to an lung. Therefore if endotracheal tube obstruction may occur, early detection and treatment is very critical. A 53-year-old male patient underwent acute unilateral obstruction of bronchus immediately after inserted endotracheal tube, so he revealed hypoxemia, hypotension, but smooth operation and anesthetic care was progressed overall owing to endotracheal tube suction and replacement of tube.

A posterolateral intertransverse process fusion is generally considered to be one of the most common types of lumbar fusion and a reliable procedure. It is reported that establishment of blood supply is important for nutrition as well as for formation of new bone during bone graft healing. Since the major interosseous blood supply for vascularization of autogenous bone graft is originated from the upper and lower transverse process, the one of the transverse process can he related to rate of bony union. It can be constructed that different union rate can result from the differences in transverse process areas. In this study, the area of the transverse processes of L5 were measured in normal adult. For this purpose, Ushikata area-Curvimeter (X-PLAN 360) was used. In Results, there was no significant differences in the age, but there was differences in the gender.
